Heat and Mass Transfer The rate of energy emission from unit surface area through unit solid angle, along a normal to the surface, is known as Emissivity Transmissivity Intensity of radiation Reflectivity Emissivity Transmissivity Intensity of radiation Reflectivity ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer Two long parallel surfaces each of emissivity 0.7 are maintained at different temperatures and accordingly have radiation heat exchange between them. It is desired to reduce 75% of the radiant heat transfer by inserting thin parallel shields of emissivity 1 on both sides. The number of shields should be Three Four One Two Three Four One Two ANSWER DOWNLOAD EXAMIANS APP
